What to do if you're one of the plumbers
- Lean into the work AI isn't doing. In the usage data, core tasks such as "Shut off steam, water, or other gases or liquids from pipe sections, using valve keys or wrenches" show no observed AI use. Building depth there is the most defensible part of the role.
- Get fluent with AI on the tasks it's already touching. The highest-coverage task here is "Review blueprints, building codes, or specifications to determine work details or procedures". People who can check, direct and sign off AI output on tasks like this are likely to be more valuable than those competing with it.
- Watch hiring, not headlines. UK adverts for this role are down on a year ago, but compare with the wider market: all UK adverts are -3.4% on the same basis (dashboard). A fall that matches the whole market is a cycle, not an AI story.
- Check the claims. When a company says AI replaced jobs, look at its grade in our ledger - many announcements are mixed or AI-washed.
